Hi guys,
I was hoping someone could help me.
I've just purchased a Sapphire Crossfire 790gx motherboard, Phenom II x4 955, a Sapphire ATI Vapor-X 4890, along with many other brand spanking new components. I've not had to build a PC in a fair few years, and am totally confused as to what the PCI-e Switch card is for - it came with the 790gx motherboard.
Reading the manual, it says, "Install Switch Card to PCI-Express2.0 x16 graphics slot can double PCI-E X16 VGA card installed transfer rate up to 16 lane; 16Gbyte/sec."
That is complete gibberish to me. If someone could tell me when and why to install a switch card in the 2nd PCI-E slot I would be really grateful. My initial reaction is I should install it when not running 2 cards in Crossfire so that one slot is X16?
But some clarification wouuld be great.
Many thanks,
Wells
